Abstract.Kemenyan is the most famous local tree species from North Sumatera. Kemenyan known as rosin producer that is very valuable for their use in pharmacheutical, cosmetic, food preservatives and vernis.Based on its history, there were only two species of kemenyan those were kemenyan durame and toba, but in its natural distribution we also found others that alleged the different species with previous grouping. The objectives of this research were: (1). To get information about morphological diversity of kemenyan in North Sumatera and (2). To get information about phylogeny clustering based on morphological characters. Data was collected from direct observation and morphological characterization,based on purposive sampling technique at Pakpak Barat, North Sumatera. Morphological characters were examined using descriptive analysis, phenotypic variability using standard deviation, and cluster analysis using NTSYS Spc 2.0.2. Result showed that there were several differences between four species of kemenyen (batak, minyak, durame and toba) according to 61 observed characters including flower, fruits, leaf, stem, bark, crown type, wood and the resin. From NTSYS Spc 2.0.2 analysis and both quantitative and qualitative characters, kemenyan were clustered into two groups consisting of kemenyan batak, durame and toba in similar group, while kemenyan minyak stand alone in another groups.
